Blast homepage and Selected Search Pages

Items Unique to Translated Search Pages
The page layout for translated BLAST search pages is the same as 
“
Standard Protein BLAST.
” 
However, they do con-
tain a few program
-
specific parameters. 
• 
Translated blastx search: 
In the 
“
Enter Query Sequence
” 
section, 
a 
“
Genetic code
” 
field (
A
) is present under the 
“
Choose File
” 
button 
specify the codon table used in the translation of the input nucleo-
tide query. Choose a code appropriate for the source of the query 
sequence. The remaining sections are the same as the 
“
Standard 
Protein BLAST
” 
page.
• 
Translated tblastn search: 
The page layout is the same as the 
“
Standard Protein 
BLAST
” 
search page. The key difference is that the Database field lists available nucle-
otide databases instead.
• 
Translated tblastx search: 
The layout differences are the presence of the 
“
Genetic 
code
” 
field (
A
) similar to the blastx page. The databases listed under the Database pull
-
down menu are the nucleotide databases. Note, the 
“
Enter Query Sequence
” 
takes nu-
cleotide queries.
Other Search Pages
 
BLAST search pages under the 
“
BLAST Ge-
nomes
” 
category (
B
) differ from these under 
the 
“
Basic BLAST
” 
category only in the data-
bases they access. The link names clearly indi-
cate the source organism of the database the 
search will target. Most will be custom pages generated upon user input (
C
) 
with the best available genome dataset for the input target organism. 
The 
“
Specialized BLAST
” 
category contains different types of search pages, 
designed for specific tasks. Table 3 below summarizes the functions these pag-
es provide.
